Fine Ceramics, sometimes referred to as "advanced ceramics," are engineered materials that support the development of cutting-edge technology.

Conductivity to Allow Electricity to Pass Through

Insulation

Though Fine Ceramics (also known as "advanced ceramics") are generally insulating materials that block electricity, semiconductor ceramics can be created to conduct electricity depending on their temperature and the level of voltage applied.

Applications: Temperature sensors, temperature measuring devices and solid oxide fuel cell.

Description

Conductivity

Conductivity is a property that allows electricity to flow through a material. Fine Ceramics are insulating materials in general, but some varieties exhibit electrical conductivity according to changes in temperature.
A thermistor is an electronic component utilizing a property in which electrical resistance decreases as temperature increases, allowing electricity to flow more easily when the material gets hot. These devices are used in sensors that monitor temperature changes and in equipment designed to prevent electronics from overheating. A varistor is a similar component that possesses a property in which resistance decreases as voltage increases. Varistors are used to protect electronic circuits from excessive voltages.

The term "Fine Ceramics" is interchangeable with "advanced ceramics," "technical ceramics" and "engineered ceramics." Use varies by region and industry.
